Proposed are a method and device for receiving an EHT PPDU on the basis of a tone plan in a wireless LAN system. Specifically, a reception STA receives the EHT PPDU from a transmission STA through a 320 MHz band. The reception STA decodes the EHT PPDU. The EHT PPDU includes a control field and a data field. The control field includes information about a pilot tone. The information about the pilot tone includes allocation information indicating that a first pilot tone for the 320 MHz band is configured by repeating a second pilot tone for an 80 MHz band defined in an 802.11ax wireless LAN system. The first pilot tone is received in a data field on the basis of the allocation information.
Legal claims defining the scope of protection, as filed with the USPTO.
5. The method of claim 4, wherein, when the 320 MHz band consists of first and second 160 MHz bands, and the first and second 160 MHz bands are non-contiguous to each other, a tone index of a third pilot tone for the first and second 160 MHz bands includes an index obtained by adding −512 to a tone index of the second pilot tone and an index obtained by adding +512 to an index of the second pilot tone.
7. The method of claim 2, wherein, when the EHT PPDU is transmitted to one receiving STA, the second tone plan is configured with a 996-tone RU, and the 996-tone RU is an RU including 996 tones.
8. The method of claim 7, wherein a tone index of the second pilot tone is set to ±{24, 92, 158, 226, 266, 334, 400, 468}.
16. The method of claim 15, wherein, when the 320 MHz band consists of first and second 160 MHz bands, and the first and second 160 MHz bands are non-contiguous to each other, a tone index of a third pilot tone for the first and second 160 MHz bands includes an index obtained by adding −512 to a tone index of the second pilot tone and an index obtained by adding +512 to an index of the second pilot tone.
